A long month battle

We have been with ADT for a while And admittedly the service has not been great from the start. We lodged a complaint with the call centre about a month ago about the delay on response time. We never heard back. We lodged another complaint about sending a guard to the house unannounced after I instructed the call centre not to as it was a false alarm causing my fiance and their guard to put their lives in danger as they a were both armed Ealing around the yard. We then had am incident where it took 20 minutes for a guard to arrive (or so I was told) as the guard never arrived and the call centre phoned me to tell me he was there and everything was fine. I was home and he never arrived. We asked for an investigation to be done. Again no feedback. We then had an alarm go off last night and nobody phoned or arrived! We called the manager and he said we must pay a R880 call out fee because someone needs to come and check our alarm system! We just tested it and it works fine, they have **** to us endlessly and evaded every question we have asked. It is undoubtedly the most useless response call centre/ armed response company I have ever had to put up with! Shocked if I get a response!
